ROBERT TINSLEY, OF PULLMAN, ILLINOIS, ASSIGNOB TO THE PULLMAN COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CAR-ROOF CONSTRUCTION.

Illinois, have invented certain new and useful Improvements in Car-Roof Construction,

of which the following is a specification.

The present invention concerns improvements in railway car body constructions, and

pertains more particularly or especially to the roof constructions, its leading aim and l object being a metallic roof structure of simple design, economical to manufacture, rain and weather proof, and whichwill not have a tendency toopen up the seams due to contraction and expansion of the parts, or due to any stra-ins to which they may be subjected.

Other features of novelty and improvement will be made apparent from the following detailed description of a desirable embodiment of the invention, which has been illustrated in the accompanying drawings, forming a part of this specification, and throughout the various views of which like reference characters refer to the same parts. In these drawings-Figure 1 is a vertical cross-section through the top portion of the car, certain parts being omitted for clear-4 ness of illustration; Fig. 2 is `a fragmentary` side elevation of the construction shown in Fig. 1; Fig. 3 is a fragmentary plan view of a portion of the car roof; F1g. L1 is a perspective view of one of the loose carlines; Fig. 5 is a perspective view of one of the roof carlines secured to the roof plates; Fig. 6 is a perspective detail of a portion of the lower deck; Fig. 7 is a fragmentary crosssection through the the roof or upper deck on line 7-7 of Fig. 8; Fig. 8 is a cross-section on line 8 8 of Fig. 7 and Fig. 9 is a fragmentary perspective view of the top central portion of the roof.

In this particular embodiment of the invention it will be apparent from a consideration of Fig. 1 that the side upright pressed sheet-metal channel posts 10, 10 have their upper ends 11, 11 somewhat reduced in .depth and curved or bent` inwardly to form the carlines for the lower deck or roof portionof the car structure, the inner ends of such carlines being connectedy together by the pair of longitudinal angle deck sills 12, 12 to which the flanges of such carlines may be riveted. Just below the Specification of Letters Patent.

. curved surface of curved carline latter on each together by longitudinal Z-bars 13 whosey Inner flanges are riveted to the outer flanges portions 11 of such posts, the

of the posts, while the outer flanges of the.

former constitute convenient means for the attachment of the metallic side sheathing 14, and also for the curved metal plates 15 formmg the lower deck or roof. 'lhe upper deck or top roof portion of this car structure is supported on short upright posts 16, 4which have their lower ends suitably fastened' to the deck sills 12, and the combined side posts and 'carlines 17 which are fastened at the places of the transverse curved joints or seams of the deck plates have their vertical flanges extended upwardly beyond the top 0 the lower deck or roof, as 1s clearly shown in Fig. 6. The roof plates 15 have upturned flanges 18 disposed against the opposite sides of the upper portion of the vertical flange of the combined post and carline 17, and in order to unite such arts and form a'weather-tight joint I prov1de a hollow cap strip 19 which fits over the carline and the two flanges and is riveted thereto at intervals, as is clearly illustrated. It will be observed that this joint or seam follows the curve of the deck and assists rather than hinders the proper shedding of the rain therefrom. At its top end .each of these lower deck upstanding seams is covered by a pressed metal member havin a hollow rib 20 accommodating the carline, the two flanges 18, and the coveringstrip 19, ysuch member also having a flange or plate p0rtion 21 riveted or otherwise desirably secured to the outside finish plate 22 between the lower and upper decks.

The top ends of the upper posts 16 have associated therewith the longitudinal inverted pressed sheet-metal channels 23, to which are attached the flanged ends 24 of the top deck channel carlines 25,'the top edges of whose sides have outstanding flanges 26 on which the roof plates 27 rest, such carlines being depressed at their central portions at 28 for the accommodation of a longitudinal bar 29 disposed centrally of the car and extending from one end to the other thereof.A

These channel carlines 25 are suitably spaced apart and are not riveted or otherwise directly connected to the roof or deck plates 27. The top deck carlines 30 beneath and associated with the transverse seams or Patented Nov. 7, 1911.-

tudinal'bar 29, and have a laterally-turned ear 32 at each end for the attachment of the n carline to the channels 23 or the posts 16.

It is to be understood that both styles of greater depth at the center than at the ends, such reduction in depth being graduated, as clearly indi- The vertical flanges or plate portions of the angle carlines 30extend upwardly between the adjacent edges of the plates 27, such edges being upturned to provide flanges 33 lying on oppos1te sides of each of such angle directly Figs. 7, 8 and carlines, and these three parts are connected together and protected by an inverted channel cap strip 34 which is riveted to the parts housed within it at intervals for` the proper and ellicient securing together of these memb'ers. The longitudinal edges of such' roof 'l or deck plates 27 are also provided with up- 25 wardly-bent flanges 35 disposed on opposite sides of the vertical plate portionof the inverted longitudinal T-bar 29, and such 'oints are covered by inverted channel longitudinal cap strips 36 which receive within their hollow interiors the flanges 35 and the portion of the bar 29 between them, such cap strips'being riveted to these parts, as is clearly illustrated. In order toform a tight joint at the junctions of these angularlydisposed seams or joints at the center of the car roof, I provide each of such junctions with a pressed sheetfmetal cap plate 37 bent or pressed so as to have two hollowribs 38 and 39 intersecting at right angles to one another and adapted to accommodate the adjacent portions of the cap strips 34 and 36 and the parts housed Within the latter, rivets 40 being employed to extend through all of such parts, as is clearly indicated in 9. Also, as I have illustrated, the main portion of the cap plate 37 rests that'at the intersections of these joints or seams on the top deck or roof of the car a construction is employed which effectively prevents leakage and securely holds the parts together.

Whereas I have herein set forth one particular embodiment of this invention, I wish to have it understood that .the invention is susceptible of a considerable number of emon the tops ot the deck plates 27 so bodiments and that itis not limited to the exact and precise structural details herein' shown and described. Some of the important featiires of this invention are the construction of a metal car roof in which a part only of the carlines are directly attached thereto; which permits the roof to contract and expand readily without strain upon any seams; which may decrease the amount of work in constructing a car of this kind; and in addition facilitates the removal of one of the roof plates if the same becomes injured or damaged. Another feature of the invention is the construction of a car of this type having upstanding roof seams dis osed in the general direction of the shedding of the water and the housing or fastening of a part of the carlines in the joints or seams between adjacent roof plates. These with other features of novelty and improvement will doubtless be readily apparent to those skilled in this art.

-If desired the cap plates 37 may be made of copper, brass, or other suitable metal brazed or welded in place, being effectively secured or fastened to the parts which they cover and protect. I n such case the showing or illustration would differ from that presented only in the omission of the rivets 410.

I claim: I

In a railway car roof construction, the

combination of channel carlines of substanl tial width, other carlines having verticallydisposed plate portions extending above the top surface of the channel carlines an amount substantially equaling the depth of the roof seams for the roof plates, a ridge pole supported on said carlines and having a vertical rib, metal roof plates disposed between said plate carlines and resting upon and un'attached to the tops of said channel carlines, said roof plates having upstanding flanges disposed on opposite sides of the plate portions of said other carlines and on opposite sides of the -vertical rib of said ridge pole, and inverted U-shaped cap strips covering and protecting the flanges of said roof plates, the intermediate parts of the plate carlines and the rib of the ridge pole, substantially as described.
